JACOBUS PHILIEPUS KAUSE, OF CHICAGO, ILLINOIS.

FENDER FOR SHIPS.

To all whom t may concern Be it known that I, JAconUs PHILIPPUs KAUsn, asubject of the Queen of the Netherlands, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful improvements in Fenders for Ships, oit which the following is aspecification.

rlhis invention relates to fenders for ships designed to prevent injuryto the hull from collision or other causes.

It is the object of the present invention to provide a novel andimproved fender ot the kind stated, which is simple in con struction,and which will operate in an e'ii'ective manner to absorb the shock orjar resulting from a collision;

Vith this object in view, the invention consists in a combination andarrangement of parts to be hereinafter described and claimed, referencebeing had to the accompanying drawings, in which Figure 1 is asideelevation of a ship equipped with my improved fender; Fig. 2 is anelevation of a fragment of the fender drawn to an enlarged scale; Fig. 3is an elevation showing the inner side of the fender, one of the fendersections being shown separated; Fig. 4l is an enlarged horizontalsection on the line .lv-l of Fig. 1; Fig. 5 is a longitudinal section onthe line 5 5 of Fig. 4; Fig. (3 is a cross-section on the line 6*@ ofFig. 4l; Fig. 7 is a hori- Zontal section showing the shock absorbingmeans for the rear portion oil the fender, and Fig. S is a cross-sectionon the line S-S ot' Fig. 7.

Referring specifically to the drawings, l0 denotes the hull oi" a shipequipped on each side with a fender constructed and arranged inaccordance with the present invention. The fender is composed of a4series of buffer plates 1l extending along both sides of the hull fromthe bow to the stern. The fender is located above the water-line torender it less exposed to wear. On the outside of the hull is rigidlymounted a steel belt 12 having lugs 13 at regular intervals to receiveand hold pivot pins 121-. To the lugs are pivoted, by means of the pins,the inner ends of links 15. These links are substantially H-shaped, theybeing composed of top and bottom arms which are connected by a web, asclearly shown in Fig. (3. The inner ends of the arms straddle the lugs13 and the pins 14 pass therethrough. The outer ends Specification ofLetters Patent.

of the arms are connected to blocks 16 which are connected end to end byhinge joints and carry the buil'er plates 11, said plates being .mountedon the outer faces of the blocks. One end ot each block has verticallyspaced hinge knuckles 17 and the other end a hinge knuckle 1S. '.lheknuckle 18 lits the knuckles of the adjacent plate, and by means of apin 19 passing through said knuckles, a hinge connection between theblocks is made. rlhe outer ends oit the arms of the links 15 straddlethe hinge connections and the hinge pins 19 pass through said ends ol'the arms. Thus, it will be seen that the fender is a flexible belt whichis held normally spaced from the hull by means of the links 15.

l'n the stem of the hull 1() is mounted a stuliing box 20 through whichpasses the stem Q1 of a plunger 22 mounted for reciprocation in acylinder 23 suitably supported in the hold or on one of the decks of theship. The plunger stem extends forward :trom the bow ol" the ship andcarries at its outer end a head 9.4L having ears on opposite sides towhich the blocks 1G of the fender belt, at the forward ends thereof, arepivotally connected, as indicated at 25. Thus the tender belt alsoconnected to the plunger stem, the purpose of which will be presentlymade clear. The intermediate portions of the plunger stem 2Q passesthrough a housing 26 containing two spaced partitions Q7 provided withopenings through which the plunger stem passes. This housing and thecylinder Q23 are supported on a suitable bed 2S, between. which latterand the hull 10 eX- tend braces 29.

Between the partitions 27, the plunger stem 22 carries two spacedabutments 30, and between these abutments a spring 31 is coiled aroundthe plunger stem. The diameter oi this spring is such that it cannotpass through the openings in the partitions, said openings howeverallowing the abutments 3() to pass therethrough. Thus it will be seenthat the spring is compressed when one of its ends reaches a partitionand the plunger stem continues to travel in the same direction. Theabutment 30 first passes through the opening in the partition, and thenthe spring end comes in contact with thc partition. This action takesplace when the plunger stem travels in either direction, the forwardpartition stopping the spring when the plunger stem travels forward, andthe rear partition stopping the spring when said stem travels rearward.The function of the spring is to resist the travel of the plunger stemfor the purpose to be presently described.

The cylinder 23 has inletports 32 in its ends for compressed air orother fluid pressure. Valves 33 Vcontrol these ports. The ends of thecylinder also have relief ports leading to av safety valve 35 whichopens to allow escape of excess pressure.

When the parts are in their normal position, the plunger 22 is at theforward end of the cylinder 23 in which position of the plunger, thehead 24 of the stem 21 is held in advance of the bow of the ship, andthe fender plates 11 are held spaced from the sides of the hull, thelinks 15 extending diagonally between the hull and the fender, as shownin Fig. 4. The spring 31 is inactive, it being held between theabutments 30.

Vith the parts in the hereinbefore described position, if a head-oncollision takes place, the plunger stem 21 is forced rearward, itsrearward travel being resisted by the spring 31 when the latter reachesthe rear partition 27. Compressed air or other fluid under pressure isalso admitted into the cylinder 23 to the rear of the plunger 22,whereby the rearward travel of the stem is still further resisted, andthe jar and shock resulting from the collision is absorbed, therebypreventing injury or damage to the hull 10 or materially reducing thesame. If the fender belt is struck from the side the oblique position ofthe links 15 tends to advance the stem, this movement being resisted bythe spring. rlhis will give the watch sufficient time to admit fluidpressure in front of the plunger 22, whereupon the stem is retracted,and the links spread the fender belt, as shown dotted in Fig. 4, toresist the shock.

In order to provide a means for absorbing the shock if the rear end ofthe fender is struck, the mechanism illustrated in Figs. 7 and 8 isprovided, the same comprising a cylinder 3G in which a plunger 37 works,said plunger having a rod 3S which carries a head 39 at its outer end,said head being connected to the fenders by means of links 40 and levers41. The head 39 is mounted in a suitable slideway 42. The cylinder 3G,in front of the plunger 87, has a fluid-pressure inlet 43. Behind theplunger the cylinder is open. The levers 41 are pivotally connected tothe hull 10, as indicated at 44, and their inner ends are connected bythe links 40 to the head 89. The outer ends of the levers are connectedto the rearmost blocks 16 of the fender belt, as indicated at 45.

In operation, when a side section of the fender belt is struck, the beltwill swing toward the hull, whereupon the lever 41 through the linkconnection 40 will slide the head 39 rearward, pulling the plunger 37 inthe same direction. New, upon turning Huid-pressure into the cylinder36, in front of the plunger 37, the head 39 is pulled forward, whereuponthe levers 41 are swung in a direction to expand the fender belt toresist the impact of the shock.

The fender structure herein described provides an eflicient safeguardagainst injury to the hull from collisions, and as the structure isdevoid of complicated parts liable to get out of order, the fender isalways ready to serve the purpose for which it is designed.
